To all 1072,0721, it 77mg concern;

Be it known that W i ARLE PALMER and J OHN WILLIAM DErIMEAn," of Akron, in

1 upper roll in respect to size and arrangement 5 of segments,but as shown it is of smaller diameter and has two sets of fixed segments the county of Summit", and in, the State of Ohio, have invented certain new and useful Improvements in Paper-Blank Feeding and Scoring Machines; and we do hereby declare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, in wh ich Figure 1 is a top plan view of a machine embodying our invention; Fig. 2, a side elevation thereof; Fig. 3, a vertical section, and Fig. 4 a perspective view of the combined 1 5 feeding and scoring rolls.

Letters of like name and kind refer to like parts in each of the figures;

The object of our invention isto provide a sheet feeding and scoring machine of simple" construction, one capable of easy and" ex tensive adjustability for-blanks of different lengths and of accurate work; and to this end said invention consists of the machine having the features of construction as hereinafter specified. V

In the embodiment of our invention which we have selected for illustrationa frame is employed comprising a base or bed A and vertical sides a and a. Mounted in bearings in the latter is a pair of rolls B and O, placed one above the other and geared to rotatejn unison by gear-wheels D and D at one end thereof. One-half of the circumference of the upper roll is provided with aseries of fixed 3 5 circumferentially-extending raised or rib-like segments 1) and b, that at one of their ends are joined to a longitudinally-extending rib b, which reaches from end to end of the roll and upon the face of which is a longitudi- 40 nall'y-extending scoring rib or ridge b Attached to theIperiphery of the roll by screws E and E is a series of other circumferentiallymovable rib-like segments b? and b separated by spaces each equal to the width of one'of the segmentshso that the two. sets of segments may interlock. The segments 6 and b are united at one end, and extending across tween the two sets of fixed segments.

the rib b rangement and connection of the movable 'them and their connecting-piece is a scoring rib or ridge 1).

" The lowerroll O may be a duplicate of the and'c and movable segments a and c, that are connected at their mid-length, so that their opposite ends may enter the spaces be- Screws G and G secure the movable segments to the roll. Extending from end to end of the lower roll is a groove 0 to cooperate with the scoring-rib b on the upper roll, while to cooperate with the rib b on the shiftable segments is a groove 0 in the face of the segments 0' and c and the connection between them.

It will be seen by shifting the segments L and b of the upper roll in a circumferential I direction within the limits wherein they continue to overlap the fixed segments that the extent of circumferential feeding-surface of the roll will be varied, though kept continuous, and so enabling variation in the quantity of paper fed, and that the distance between the scoring-ribs will be varied, enabling the position of the scores or creases to be variedlto suit the" length of paper fed. The segments 0 and c of the lower roll are shifted circumferentially to place the scoring-groove c inposition for cooperation with It will be noted that by the arsegnnents whereby the scoring rib or groove may'be applied thereto the one pair of rolls servesboth for feeding and scoring and one adjustment serves to both fix the extent of feed and the relative position of the scores or creases.

On the upper-roll shaft is a pinion H, that meshes with a gear I, loosely mounted on a stud-shaft K, and fastened to tbe'gear is a ratchet-whcel L, with the teeth of which engages a pawl M, carried by a disk N onv the shaft K, to which an oscillatory motion, is imparted by a pitman 0, connected w'ith'suitable operating means.

The two rolls by the described gearing are revolved intermittently, and their starting and stopping positions are with the space on the upper roll that has no segments adjacent the lower roll. Into the space thus provided between the rolls the forward edge of the blank to be fed and scored is thrust, and for gaging it a stop device is provided comprising, preferably, three arms P, P, and P, having each an upturned endp and attached to a horizontal rock-shaft Q, by the movement of which the arms may be depressed to remove their ends from the path of the blank or raised to interpose said ends in such path. The ends p, p, and 19, respectively, play through slots r, r, and rin light bars or rails R, R, and R, which support the blank and over which it passes when moved onward by the feed-rolls. The movements of the stoparms in proper time with the feed-rolls are secured by means of a cam S on the upperroll shaft and a crank-arm T on the rockshaft Q, one' end of which arm carries a roller t, that engages the cam.v

It will be seen that by the location of the feed-gage or stop device on the side of the rolls B and O opposite that from which the blank is fed there is no danger of accidental derangement of the position of the blank before the blank-engaging portions of the rolls engage therewith, because no movement of the blank by the operator is necessary to place the blank in position for engagement by the rolls after the blank is arrestsd by and engages the stop device.

The object of the set of fixed segments on the lower roll 0 and the portions of the movable segments interlocking therewith which come opposite the space on the upper roll having no segments is to provide a smooth or continuous supporting-surface for the blank when thrust between the rolls, so that there will be no projection for the paper to strike.

In addition to the two transverse scores or creases made by the two rolls it is desired to score or crease the blank longitudinally, and for this purpose there are several pairs of scoring-rolls Uand U, mounted, respectively, on upper and lower shafts V and V, journaled in hearings in the frame sides a and a. After passing from said rolls U and U the blank has glue applied to one edge of it by a glue-wheel W ona shaft X, journaled in bearings in the frame sides a and a, which wheeltakes glue from a pot Y in an ordinary way. Above the glue-wheel on a shaft Z, also journaled in bearings on the frame sides a and a, is a feed-wheel A, and on said shaft is another feed-wheel B, that coacts with a feedwheel 0 on the glue-wheel shaft. The blank next passes between and is cut into strips by pairs of circular cutters or knives D and D, mounted, respectively, on shafts E and E, journaled in hearings on the two frame sides a and a. The various shafts carrying the scoring-rolls, the glue and feed wheels, and the cutters are geared together by'a train of gears, and all are continuously driven by power taken from a suitable source.
